The@ is just that, meaning it must appear after at least one alphanumeric character for the whole pattern to succeed. @就是意味着它必须出现在至少一个字母数字字符之后,这样整个模式匹配才能成功。
The patients were asked to look at the screen, which contained a6-by-6 matrix with a single alphanumeric character inside each square. 病人被问及在屏幕上看到了什么,屏幕上每一个方块中显示单一的数字字母样的字符。
Now the system can achieve a recognition ratio of 94. 61%. The experimental result shows that the BP neural network can be used for handwritten alphanumeric character recognition successfully. 目前识别率为94.61%,实验结果表明,BP神经网络可成功地用于手写数字字符的识别问题。
Characters recognition includes Chinese character recognition and alphanumeric identification: the Chinese character recognition by the template matching and character recognition combining matching features improved identification methods. 并且把车牌字符分为汉字识别和字符(字母与数字)识别:提出把汉字识别的模板匹配与字符识别的特征匹配相结合的改进的识别方法。
This system used three BP network model, in the procedure realizes in the process the repeated test, had the high recognition rate to the car license alphanumeric character. 字符识别系统。采用三层BP网络模型,在程序实现过程中反复试验,对车牌中的数字字符有较高的识别率。
